【摘要】 目的:研究大孔吸附树脂DiaionHP-20富集纯化南山茶种子抗原发I型骨质疏松有效部位的工艺条件。方法:以南山茶种子中总黄酮和多酚的洗脱率和纯度为指标,考察DiaionHP-20的吸附量、载样量、乙醇洗脱浓度、乙醇洗脱用量等参数。结果:DiaionHP-20的吸附量总黄酮为59.5mg.g-1,多酚为23.9mg.g-1。最佳工艺是药液上样量为10.5倍树脂重量,使用3倍树脂质量的蒸馏水洗去水溶性杂质,13.5倍树脂质量的25%乙醇洗脱总黄酮和多酚。结论:Diaion HP-20能够很好地纯化南山茶种子中总黄酮和多酚,工艺简单,成本低,适于规模化生产。更多还原

【Abstract】 OBJECTIVE:To study the technical conditions and parameters of DiaionHP-20 macroporous adsorption resin for the purification of the anti-PMOP(primary Type I osteoporosis) active fraction from Camellia semiserrata seed.METHODS: With the elution ratios and purity of total flavonoids and polyphenol from Camellia semiserrata as indexes,the technical parameters of DiaionHP-20 macroporous adsorption resin including the adsorption quantity,the loading sample,the elution concentration and volume of alcohol were investigated.RESULTS: The adsorption quantity of DiaionHP-20 macroporous resin on total flavonoids and polyphenol were 59.5 mg·g-1 and 23.9 mg·g-1 respectively.The optimal technical conditions were as follows:the quantity of drug was 10.5 times that of resin;water-soluble foreign substance was washed off with distilled water weighing 3 times the weight of resin,and total flavonoids and polyphenol were eluted using 25% ethanol weighing 13.5 times the weight of resin.CONCLUSION:DiaionHP-20 macroporous resin had good purification effects on total flavonoids and polyphenol from Camellia semiserrata seeds.The process is simple,low cost,and suitable for lavge-scale production.更多还原
